BELL.

of which the following is a specification.

y My invention relates to new and useful improvements in alarm. oeils for use upon electric street or other similar vehicles Where it is desired to one or more Warning signals, singly or successively', as 'pre-v terred. l

The objects ot the invention are to produce an improved lform of bell, including two hammers designed tc strike singly. or alternately to give one or more signals as required; to employ a spring actuated. rack, gear, and bell-crank' lever construction for operating the gong so as to effect a sharp, clear and distinct sound; to design a bell whereby a series of sounds .may be obtained either in slow or rapid succession as the emergency requires, by aJ singlemovement of ,the4 push rod, which is desigi'ied so as to be operated either by hand or toot-power.

The invention further resides and consists in the construction and, novel combination and arrangement ot parte hereinafter more fully descr ibed, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the scope, proportion, size and minor details of construction with in the scope of the claims may be resorted to Without departure from the spirit or sacrificing any of the advantages ot the invention.

SimileA characters ot .reference denote like or corresponding parts 'throughout the several figures of the accompanying drawings forming' a part of this specification and upon which,

.Figure 1 shows a central vertical sectional elevation o my improved'bell. Fig. 2, is a vertical cross section ot same taken on line 2 2 ot' Fig. 1; and Fig. 3 is an edge view of my heli as seen from right of Fig. 1.

which is supported on a post 8, and secured to ythe outside of the casing 6.

9 is a straight vertically operatable rack, mounted in the casing and supported upon a spring 10 that tends to hold the shoulder 11 of the rack up against the top of the casing.' rlhe stem .and head 12 of the rack extends up through t-he` casing and floor in position to be pressed down against the ac-` tion of the spring by the hand or foot of an operator, to ring the bell.

The teeth of the vertically disposed rack 9 engage a pinion 13 that is loosely mounted upon a shaft 14, secured'to the sides of the casing 6. A disk 15 having a toothed peripheral edge is secured to the side of the pinion 13. A series of pins 16 are secured to the side of the disk, one pin in line with each of the teeth, and upon each of said pins .is mounted a roll 17 which together With the before mentioned teeth are designed to yengage the lugs 1S, upon the 'in termediate levers 19 pivotally mounted upon pins 20, secured to the casing. There are an uneven number of these pins and teeth and the lugs of the levers are so located with relation to the rolls as to throw the free end oi one lever out, while the other is in, causing them to operate alternately and eiiect successive strokes of the Ytwo hammers on the bell., A. spring 21 attached to pins, secured to the long end of the levers 19, serve to draw the same together and to hold the lugs in engagement with the disk and rolls. I

A pair of bell-crank levers 32 are loosely l ,spring actuated pawl 27 Iis pivotally con# nected to the outer end of each of the short arms 28 oit' the bell-crank levers, for engage ment, by the short` end 29 of the before mentioned levers 19, ind in a Way to permit a tree movement, o the' said short ends 29 past the stort arms 28, so that parts may ido return to their normal position. With the rotation ol the disk the long end of the levers 1 9 are forced, out by the teeth or pins oit the disk and the y'short arms 3() and ends.

29 of the two levers 19 und 22 are in torn thrown in against the action of the spring 25, until the Short endot the lever 1,9 slips ott of the Spring-actuated pend 27 to allow the spring Q to act, and throw the hammer of the bell-crank lever to strike the gone. Immediately upon passing over the pins of the disk, the lugs ot the levers drop into the pockets of the teeth end thus canse the short end of this leverl to move ont past the free end of the puwl 27, which is thrown back at an angle and snaps down again upon the lever (see Fig. l), thus permitting the free return ot said short ends 29 ot the lcver 19,' and the positioningjr of them in readiness for further operation.

From the foregoing construction it. will he seen that alternate operations ot the hammers upon the bell are effected and are delupward movement ot the rack 9.

signed to strike one or a dozen times aeeording to the amount of the dowi'iward and Said rack maybe shoved down against thenction of' its vspring `by either hnnd or foot power, and it moved but a short distance would cause only one of the hammers to strike, whereas a further movement would canse both to Strike once or more times, vvith both the donfnward and upward movement of the operating` rack. ln the above device, I have produced a bell which is par- Low/,oie
